The American Libraries collection includes material contributed from across the United States. Institutions range from the Library of Congress to many local public libraries. As a whole, this collection of material brings holdings that cover many facets of American life and scholarship into the public domain. Significant portions of this collection have been generously sponsored by Microsoft , Yahoo! , The Sloan Foundation , and others.
The California Digital Library supports the assembly and creative use of the world's scholarship and knowledge for the University of California libraries and the communities they serve. In addition, the CDL provides tools that support the construction of online information services for research, teaching, and learning, including services that enable the UC libraries to effectively share their materials and provide greater access to digital content.
